“…On the contrary, studies by Mehta et al (2018), where they determined the VOCs of jambolan (Syzygium cumini L.) fruits in three maturation stages, concluded that the main compounds that grant the aromatic characteristics to the fruit were karyophylene, δ-cadinene and α-fenchene. Ramos et al (2010) and Tietbohl et al (2012Tietbohl et al ( , 2014, when isolating the essential oil from different parts of the M. floribunda plant (leaves, stems and flowers), mentioned the class of monoterpenes and sesquiterpenes as the most important components. Similarly, the group a Compounds identified by comparing their mass spectra and retention indices according to the NIST library ( 2007 of hydrocarbon sesquiterpenes (40.6%) was found in greater amounts in lyophilized fruits of rumberry, of which (through the CAR/DVB/PDMS fiber) α-pinene, longicycline and α-humulene were also reported in the present study (OLIVEIRA et al, 2018).…”

“…Rumberry is widely cultivated for its edible fruits, which have unique organoleptic characteristics, due to their high content of vitamin C and antioxidant action (PINHEIRO; ALMEIDA; SILVA , 2011;SILVA et al, 2012). They are relevant in the chemical composition of the essential oils of leaves, flowers and stems, in addition to being rich in phenolic compounds and having excellent biological functions, including antimicrobial, anticholinesterase, antioxidant, antitumor and insecticide (APEL et al, 2006;RAMOS et al, 2010;TIETBOHL et al, 2014).…”

The composition of the volatile profile of rumberry fruits (Myrciaria floribunda) was determined using solidphase microextraction in headspace mode and gas chromatography, coupled with mass spectrometry. The PA (polyacrylate) and DVB/CAR/PDMS (divinylbenzene/carboxen/polydimethylsiloxane) fibers were optimized for the extraction parameters (agitation, extraction time and temperature), in order to select the fiber with the highest number of isolated compounds. A total of 48 volatile compounds were identified using HS-SPME/GC-MS present in the ripe fruits of rumberry. The volatile compounds were classified into five chemical classes, the majority belonging to the sesquiterpenes class (71%). In addition, it was possible to verify that the fiber coated with polyacrylate (PA) had better performance, allowing for the extraction of a greater number of volatile compounds (n = 35). The extraction conditions that allowed the isolation of a greater number of volatile compounds corresponded to times greater than 26 minutes and temperatures above 85 °C, with agitation of 79 rpm for the PA fiber. Likewise, it was found that the hydrocarbon sesquiterpenes was the chemical class most present in the fruits, which is mainly related to the volatile profile of rumberry fruits.

Myrciaria floribunda, also known as rumberry, is a tree native to the Brazilian Atlantic Forest, where its fruits have the potential for commercial use. This study evaluates the antioxidant potential, determines the phytochemical profile, and chemically characterizes the rumberry fruit. Accessions were sampled from the Rumberry Active Germplasm Bank of the Federal University of Alagoas, Brazil. Physical characteristics, chemical characteristics, and phenolic compound content were analyzed. Chemical profile characterization was carried out using PSMS. Accessions had an average weight of 0.86 g. Accession AC137 presented a higher pulp yield (1.12 g). AC132 and AC156 had larger fruits, AC137 showed greater firmness (5.93 N), and AC160 had a higher and total phenolic content ratio (279.01 ± 11.11). Orange-colored accessions scored higher in evaluated parameters, except for AC160 for phenolic content. Thirty-two compounds were identified on positive ionization mode and 42 compounds on negative ionization mode using PSMS. Flavonoids, followed by the derivatives of benzoic acid, sugars, and phenylpropanoids, were the most prominent. Myricitrin, quercitrin, and catechin stand out as flavonoids that have been reported in previous studies with antioxidant and antimicrobial properties, in addition to health and therapeutical benefits, demonstrating the potential of the rumberry fruit.

Rhipicephalus (Boophilus) microplus is responsible for reducing animal welfare, causing a drop in productive performance and transmitting hemoparasites. The main strategy of tick control is application of synthetic acaricides. However, parasite resistance to these compounds is a major concern. Therefore, the acaricidal and repellent in vitro effect of the Ocotea elegans essential oil on larvae and adult females of R. (B.) microplus were evaluated. The larval packet test (LPT), larval repellency test (RT) and adult immersion test (AIT) were performed. The essential oil was analyzed by gas chromatography (GC/FID) and the structure of the oil's major constituent (92.2% sesquirosefuran) was elucidated by nuclear magnetic resonance. In the AIT, efficacy higher than 90% was detected from the concentration 25 mg/mL upward. In both LPTs performed after 48 h, only the 100 mg/mL concentration resulted in mortalities above 70%. On the other hand, the essential oil caused an average of 95.8% repellency from 0.78 to 100 mg/mL. The LC in the two LPT (48 h) tests were 59.68 and 25.59 mg/mL, respectively. The LC and LC in the AIT were 4.96 and 17.37 mg/mL, and in the RT they were 0.04 and 1.24 mg/mL respectively. We conclude that the essential oil of O. elegans leaves has a significant acaricidal effect on engorged females and on larval repellency of R. (B.) microplus ticks, and can be a promising alternative for the control of this ectoparasite.
